Go 1.20rc1 support?

[atc0005]

I'm seeing the following behavior when running golangci-lint within the Go 1.20rc1 Docker image:

# golangci-lint run

I tried:

• v1.50.1 (via install script)
• building from source (master branch)

[atc0005]

Relevant:

• go1.20 support #3414
• typecheck: support Go 1.20 #3420

Update (FWIW):

As of ldez@1af8a00, golangci-lint builds/runs within a Go 1.20rc2 Docker image. See #3414 for current details.
